Improvement in valves for railroad-tanks



UNITED STATES PATENT QEEIGE CORNELIUS S. WEBBER, OF BANGOR, MAINE.

IMPROVEMENT IN VLVES FOR RAILROAD-TANKS.

Specification forming part of Letters Patent No. 146,37] dated January 13, 1874; application tiled n December 16, 1873.

To all whom it may concern:

Be it known that I, CORNELIUS S. WEBBEE, of Bangor, inthe county of Penobscot and State Of Maine, have invented certain new and useful Improvements in Valves for Railroad-Tanks;

' and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings,wl1ich form part of this specification.

The nature of my invention relates to an im4 provement in valves for railroad-tanks and other such reservoirs; and it consists in a spring-valve, which is operated from the outside of the tank by means of a hand-lever, the valve being guided up and down in its movements by a rod upon each side, and having its seat packed so as to prevent leaking, as will be more fully described hereafter.

The accompanying drawings represent my invention.

c represents the discharge-pipe, which extends doWn through Vthe bottom of the tank or other reservoir, and which has a conical recess, o, formed in its top to receive the rubber or other packing d. From opposite sides Of this top there rises arod or guide, e, having a screwthread cut upon their upper ends to receive the nuts g, Whichhold the tWo coiled springs down upon the valve This valve consists of a flat circular disk, h, which has openings through it, so as to pass down over the guides, and which is held down upon the packing d, so as to form. a Water-tight joint, by the springs c' and Water in the tank.` Pivoted to the top ot' the valve, between the ears Z, is the connecting-rod o, which joins the valve to the operating-lever n., pivoted to the top of the standard K Or any other suitable support.

The valves for these tanks have generally heretofore been hinged to the top of the discharge-pipe, and have only been a source of annoyance and troubleby constantly leaking. This defect my valve entirely overcomes.

I am aware that'a valve moving upon guides and held down upon its sea-t by coiled springs is not new, and I do not claim such.

Having thus described my invention, I claimv A valve for railroad-tanks consisting of the discharge pipe a, extending down through the bottom of the tank, and having a circular recess in its top to receive the rubber packing v (l, the valve l1., guides i, springs e, connectingrod o, standard k, and lever n, the parts being arranged for Operation substantially as shown and described.

In testimony that I claim i the foregoing I have hereunto set my hand and seal this 13th day of December, 1873.
